After some serous additional registering I was now able to create the archive and I moved it to the other forums with the same context. Unfortunately, it does not work. As in: I registered it with the mailing list, but no mails are showing up in the forum.
I have registered quite a number of working mailing list archives with nabble so I think I am familiar with the procedure. But two of my archives will not show any mails while the others are working fine. It is "Mapnik dev" and "Potlatch dev" in the subforum

Could someone please check what is different/wrong with those two archives?
bye
